This font is a set of cut-out layouts with which you can build 3D pixel style letters. They should all work. Just cut along the solid lines, fold along the dotted lines, put some glue on the shaded flaps, stick them together and there you go...
If you want to use this for commercial projects, please contact me: tobias (dot) sommer (at) gmx (dot) ch
I also appreciate it if you send me links/images of your non-commercial work featuring this font.
Have fun! :)
